The 17-year-old, known as Tonny, is one of the jewels in Barca's youth set-up and he further enhanced his reputation with some fine displays at the Under-20 World Cup.

The Catalan giants are keen to hang on to the youngster but the Gunners are ready to battle it out for his signature.

Arsenal have history of plundering Barca's youth teams, having swooped for Cesc Fabregas when he was just 16 years-old, developing him into a world class talent before he became Gunners skipper and was then sold back the the Catalans.

Sanabria clearly has an eye for goal, as you can see in the video below.
